What Is Injection Molding?
Injection molding is the most cost-effective way to make a plastic
part at scale. The injection molding process involves injecting
molten plastic into a mold tool, then ejecting the solidified part.
This process quickly repeats hundreds or thousands of times,
amortizing the cost of the mold tool and driving down the cost of
each unit to a few dollars or less. Since the injection molding
process uses the same mold tool for each part, it offers consistent
quality across every part. Injection molding also has the highest
variety of materials, colors, cosmetics, polishes, and surface
textures when compared to CNC machining or even 3D printing.
Custom plastic mould service is a service providing on-demand
prototype and production molding. We take a customer-first approach
which means we find the right injection molding supplier within our
manufacturing supplier network to mold the parts the way you need
them—without design compromises—at the right price point. We offer
expert consultation on each injection mold quote and project
managers on every order to move your parts from design to
production. Our team has experience in every industry, especially
medical injection molding and liquid silicone rubber molding.

Injection Molding FAQs
- What industries use injection molding?
Injection molding is used across a wide range of industries
including aerospace, medical devices, consumer goods, energy,
electronics, automotive, robotics, toys, and more.
- What is the difference between molding and printing?
With molding, plastic or metal parts are created inside a mold.
They are then removed from the mold as fully-formed parts.
3D printing, on the other hand, is an additive manufacturing
process, meaning that the part is built layer-by-layer using
processes
like deposition or sintering.
- What is the process after ordering?
After receiving the order, the statement of work is reviewed by one
of our manufacturing engineers.
A case manager is assigned, and an appropriate manufacturing
supplier is identified. A comprehensive DFM/PEG report is created
and provided for approval. Upon approval, tooling and mold
production is commenced. T1 samples are produced and shipped for
approval.
Upon approval, the remaining parts are made.
At JYH, our customers own their injection mold tools! After a run
is complete, the tool will remain at our facilities.
Tools can be shipped to you upon request; however, you will be
responsible for any associated shipping and packaging costs.
Our engineers will work with you regarding tool compatibility with
your equipment if you're unsure.
